Not feeling connected with my baby

I am 26 weeks and most of the time I forget I'm pregnant. I know I am, I am happy to be, and look forward to his arrival, but I feel no link or bond with my baby. I guess I expected to fall madly in love the second I saw that positive test. Is there something wrong with me? I feel like a bad mom. I haven't told anyone this because I feel so guilty. Please no criticizing, I already feel like a pos as it is. Does anyone else feel this way? I'm so scared of losing him and I do love him, but I just don't feel bonded. Maybe when he is actually born and in my arms I will feel it, but for now I feel awful and like I don't know him.
